Model 9139A-PCA

Safety precautions The following safety precautions should be observed before using this product and any associated instrumentation. Although some instruments and accessories would normally be used with nonhazardous voltages, there are situations where hazardous conditions may be present.

This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using the product. Refer to the user documentation for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product warranty may be impaired.

The types of product users are:

Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.

Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the instrument. They must be protected from electric shock and contact with hazardous live circuits.

Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line voltage or replacing consumable materials. Maintenance procedures are described in the user documentation. The procedures explicitly state if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel are trained to work on live circuits, perform safe installations, and repair products. Only properly trained service personnel may perform installation and service procedures.

Keithley Instruments products are designed for use with electrical signals that are measurement, control, and data I/O connections, with low transient overvoltages, and must not be directly connected to mains voltage or to voltage sources with high transient overvoltages. Measurement Category II (as referenced in IEC 60664) connections require protection for high transient overvoltages often associated with local AC mains connections. Certain Keithley measuring instruments may be connected to mains. These instruments will be marked as category II or higher.

Unless explicitly allowed in the specifications, operating manual, and instrument labels, do not connect any instrument to mains.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30 V RMS, 42.4 V peak, or 60 VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock. If the circuit is capable of operating at or above 1000 V, no conductive part of the circuit may be exposed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance-limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to limit fault current and voltage to the card.

Before operating an instrument, ensure that the line cord is connected to a properly-grounded power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.

When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input power disconnect device must be provided in close proximity to the equipment and within easy reach of the operator.

For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured.

For safety, instruments and accessories must be used in accordance with the operating instructions. If the instruments or accessories are used in a manner not specified in the operating instructions, the protection provided by the equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating information, and as shown on the instrument or test fixture panels, or switching card.

When fuses are used in a product, replace with the same type and rating for continued protection against fire hazard.

Chassis connections must only be used as shield connections for measuring circuits, NOT as protective earth (safety ground) connections.

If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use of a lid interlock.

If a screw is present, connect it to protective earth (safety ground) using the wire recommended in the user documentation.

The symbol on an instrument means caution, risk of danger. The user must refer to the operating instructions located in the user documentation in all cases where the symbol is marked on the instrument.

The symbol on an instrument means caution, risk of electric shock. Use standard safety precautions to avoid personal contact with these voltages.

The symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.

The symbol indicates a connection terminal to the equipment frame.

If this symbol is on a product, it indicates that mercury is present in the display lamp. Please note that the lamp must be properly disposed of according to federal, state, and local laws.

The WARNING heading in the user documentation explains dangers that might result in personal injury or death. Always read the associated information very carefully before performing the indicated procedure.

The CAUTION heading in the user documentation explains hazards that could damage the instrument. Such damage may invalidate the warranty.

Instrumentation and accessories shall not be connected to humans.

Before performing any maintenance, disconnect the line cord and all test cables.

To maintain protection from electric shock and fire, replacement components in mains circuits — including the power transformer, test leads, and input jacks — must be purchased from Keithley Instruments. Standard fuses with applicable national safety approvals may be used if the rating and type are the same. Other components that are not safety-related may be purchased from other suppliers as long as they are equivalent to the original component (note that selected parts should be purchased only through Keithley Instruments to maintain accuracy and functionality of the product). If you are unsure about the applicability of a replacement component, call a Keithley Instruments office for information.

To clean an instrument, use a damp cloth or mild, water-based cleaner. Clean the exterior of the instrument only. Do not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with no case or chassis (e.g., a data acquisition board for installation into a computer) should never require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factory for proper cleaning/servicing.

Figure 1: Model 9139A Probe and adapter components

Leakage paths and low current capabilities The Model 9139A-PCA Probe Card Adapter permits fast low current measurements. The short length of the connections between the DUT cables and the probe pins reduces capacitive coupling between probe pins. Capacitance is further reduced by the extended guards. This reduced capacitance permits faster rise times.

The Model 9139A-PCA extends the low current capabilities of the Keithley Parametric Test system. Leakage is minimized by using short direct connections and by extending the guards traces through to the probe blade connections. Leakage paths are also minimized by using low leakage materials for the probe card and mother board.

9139A-901-01 Rev. E / February 2015 2-3

Mother board characteristics The mother board is the interface between the DUT cables and the probe card and it accepts 64 DUT cables. It is suspended from the prober mounting hardware. Source, measure, guard, and ground (where appropriate) are terminated for each DUT cable on the mother board. Source, measure, and guard signals are kept separate for each pin and are all carried down to the probe card through spring loaded contacts (pogo pins). Four ground pogo pins take ground down to the probe card. Source and measure lines are guarded on the mother board using state-of-the-art printed circuit board manufacturing techniques. DUT cables can be routed vertically or horizontally to the mother board. Vertical routing is used when the DUT cables are routed above the top platform (head plate) of the prober. Horizontal routing is used when the DUT cables are routed under the top platform of the prober.

Probe card configuration The probe card contains 64 fully guarded measure and sense lines. It contains mounting traces for 64 probe needles. Drilled, plated-through holes are provided for interconnect pins. An unpopulated (blank) probe card is provided with the Probe Card Adapter Assembly. Additional blank probe cards are available through your Keithley sales representative.

To reduce pin-to-pin capacitance, use ceramic blade probes.

Probe needle description Make sure the probe card manufacturer complies with the probe needle specifications required by the Model 9139A (see the next two figures). Note that ceramic needles are recommended (refer to the next note), other types of needles (such as epoxy) may be used as long as they conform to the dimensions contained in the next figure. Refer to the subsequent figure for probe needle mounting information.

General installation considerations

Overview The mechanical architecture of the probe card adapter makes it possible to install the probe card adapter in a wide variety of probers. In general, the architecture consists of a mother board (see the Probe card adapter standard components (on page 2-1) figure) suspended from the prober ring. Spacers inserted between the mother board and prober ring connect the two assemblies. The length of the spacers determines the overall stack height of the probe card assembly. Modification of the mother board assembly is not required when changing the stack height or when replacing the prober ring. The ring insert diameter is changed by replacing the prober ring. The following is a list of the different probers supported by the Model 9139A-PCA Prober Card Adapter:

• Alessi • Electroglas 1034 • Electroglas 2000 Series (EG2001 and EG2010) • Electroglas 3000 Series (EG3001 and EG3010) • Electroglas 4060 • Electroglas 4080 • Electroglas 4085 • KLA 1007 • KLA 1220 • KLA/TEL P-8 • Pacific Western PW2 • Pacific Western PW3 • TAC PR8100 • Ultraprecision 680 • Ultraprecision 880 • Karl Suss • TSK A-PM-90A


3-4 9139A-901-01 Rev. E / February 2015

Safety Operator safety from hazardous voltages depends on proper installation. After installation but before energizing the unit, make sure all prober safety shields are properly in place (refer to the manufacturer of your specific prober for prober safety shield information). The light shield contains components to allow for the installation of an interlock switch (such as that provided with a Keithley S500 Series Test System)(see next figure).

Figure 5: Model 9139A PCA light shield

Do not operate the system until it is properly installed and all prober safety shields are in place. Failure to have the complete system properly installed with all safety shields in place could result in personal injury or death.

Stack height The height from the prober’s mounting seat to the surface of the chuck (stack height) is a basic installation consideration (see next figure). This stack height must equal the stack height of the probe card adapter. The stack height of the Keithley probe card adapter can be 1.330 inches (3.378 cm) or 1.492 inches (3.790 cm) depending on the type of prober and on the requirements for cable routing. Refer to Appendix B for prober specific stack height requirements. Installation may require installing mounting hardware onto the prober to ensure that the prober stack height is the same as the probe card adapter stack height (see Cable routing (on page 3-5)).


9139A-901-01 Rev. E / February 2015 3-5

Cable routing Cable routing is an important installation consideration. DUT cables can be routed above or below the top plate of the prober. For cable routing above the top plate, the DUT cables exit vertically from the probe card adapter. For cable routing below the top plate, the DUT cables exit horizontally from the probe card adapter.

The DUT cables are routed under the prober ring (of the probe card adapter). In addition, the DUT cables on some probers may exit from the left, right, or from the back of the prober. The cable exit you use depends on the type of prober and how the prober is oriented next to the system. Regardless of how the DUT cables exit from the prober, all the DUT cables must be the same length. A uniform cable length provides uniform electrical characteristics (capacitance and inductance) of the cables. This is important when performing capacitance measurements, or when measuring low level currents (see Installation procedure (on page 3-6) for more information about installing DUT cables).

Figure 6: Model 9139A Stack height

Probe card adapter configuration Confirm that your probe card adapter assembly was configured properly at the factory. Included with your probe card adapter is a copy of your completed Probe Card Adapter Order Guide and a site specific drawing of your probe card adapter.

Confirm that the probe card adapter and the drawing match your requirements as listed on the order guide. Check the following items:

• Check the DUT cables' interconnecting plug(s). Make sure they are the correct type for your system.

• Check that there are the correct number of DUT pins (count the number of cables connected to the mother board).

• Inspect the installation hardware. This hardware is specific to your prober. • Check DUT cable routing. Make sure that DUT cables are assembled correctly to the probe card

adapter. This allows the DUT cables to exit properly from prober after the probe card adapter is installed.


3-6 9139A-901-01 Rev. E / February 2015

Light shield and microscope clearance Check the light shield and microscope clearance. Most microscopes are located far enough above the probe card assembly that they do not present clearance problems when the light shield cover is installed. Some microscopes may protrude into the probe ring assembly to the area below the shield plate. This presents clearance problems. If the microscope is mounted on a pivoted arm, move the microscope aside and then install the light shield.

Installation procedure

An installed probe card may contain lethal voltages when a test is in operation. Reset the test equipment to place the PCA (probe card adapter) in a safe state.

Failure to reset the test equipment may cause injury or death due to electrical shock.


9139A-901-01 Rev. E / February 2015 3-7

Use the following procedure to install your Model 9139A-PCA Probe Card Adapter:

1. Unpack and inspect Model 9139A-PCA (see Handling precautions (on page 3-2) special handling precautions).

2. Install the probe card adapter in your prober.

The hardware supplied with your probe card adapter assembly varies depending on the type of prober you have (see Overview (on page 3-3) for a list of supported probers).

Appendix B details the specific requirements for a number of standard probers. In some instances, the prober may be modified by the supplier for a particular application. If this is the case, contact Keithley for additional information on prober requirements and available options for the Model 9139A-PCA Probe Card Adapter.

3. Route 1.9 cm O.D. vacuum hose (provided) to probe card adapter out of the way of any moving parts of your prober. Make sure the hose remains clear of any pinch points that could cut off or restrict flow through the vacuum hose. You will need to supply all connections and hardware associated with vacuum hosing, in addition to the vacuum source.

Install the PCA (probe card adapter) to a vacuum control box hose.

• Route a section of vacuum hose from the PCA through the "TO PCA" grommet (on vacuum control box).

• Connect the vacuum control box end of the hose to valve PF-1 (see next figure) and the other end of the hose to the PCA.

Install vacuum supply hose.

• Route the vacuum supply hose from the vacuum source through the "VACUUM IN" grommet (on vacuum control box).

• Connect the vacuum control box end of the hose to check valve PF-5 (see next figure). Make sure vacuum supply is at least 50.8 cm Hg.

Vent the vacuum control box to atmosphere (no connection required).

4. Making sure all power has been removed from the system, connect cables.

• Connect the DUT cables between the probe card assembly and the matrix pin cards of the Parametric Test system. Route the cables to avoid sources of electromagnetic fields. Avoid routing cables near sources of vibration or any other mechanical disturbance.

• Confirm that moving parts of the prober do not contact the cables.

Information regarding the location of connections within your system is found in the configuration drawings for your system. The User's Manual(s) for your systems contains additional information and can be referenced if required.

9139A-901-01 Rev. E / February 2015 3-9

5. Install the probe card.

• Turn vacuum control box valve to load/operate position. • Line up probe card pin 1 with pin 1 indicator on the retainer cap (see next figure). • Insert probe card into probe card retainer cap.

Two alignment pins and holes are provided along the perimeter of the probe card. These holes and pins provide for proper orientation of the probe card during installation.

• Align pin 1 of the probe card with pin 1 of the mother board. • Use alignment marking on edge of probe card retainer cap and match to same markings of

mother board support ring. Attach the retainer cap to the mother board ring. Make sure latches secure the probe ring (retainer cap will click into place).

6. Perform probe card continuity test (S400 Series System) to check Kelvin connections from the system matrix to the probe card adapter (see the Options (on page 3-10) topic for more information).

Figure 8: Model 9139A Probe card and probe card retainer

Probe card removal procedure



1. Run the probe card continuity test program (see the Options (on page 3-10) topic for more information).

2. Turn vacuum control box valve to the unload position. 3. Release the probe card retainer cap latches. 4. Carefully remove probe card and retainer cap from probe card adapter.


3-10 9139A-901-01 Rev. E / February 2015

Performance verification A matrix test is run as part of system diagnostics and requires a blank (unpopulated) probe card. Do not run a matrix test after installing each probe card. Run a Matrix Test after the probe card adapter installation to check for leakage, open connections, or shorted connections.

During leakage tests, high voltages are present on the probe card adapter.

It is necessary to install a blank probe card in the probe card assembly to run diagnostics (provided).

A blank probe card is supplied with the probe card adapter. This blank probe card must be retained by the customer. The blank probe card's clean surface provides a known, low leakage test environment. The unmodified Kelvin connections assure accurate continuity tests.

Handling and storage of the blank probe card is important. To permit accurate leakage tests, the probe card must remain unpopulated. The probe card must be stored in a protective container, in a clean, low humidity environment. Handling is important (see Handling precautions (on page 3-2)). When installing this card, handle card by the edges and do not touch the surface of the probe card.

The following list describes the programs to verify performance. For further information about running diagnostics, refer to the software or diagnostics manual for your system.

Performance Verification Using S530 Diagnotics Run the Matrix Tests from S530 diagnostics to verify probe card adapter performance.

Options

Build plate and planarization fixture A build plate and planarization fixture is available through Cerprobe. This fixture permits you to mount and adjust probes on the probe card.

Introduction This section describes how to perform maintenance while maintaining the high performance characteristics of the probe card adapter.

A minimum amount of maintenance is required for the mother board and the DUT cables. However, when maintenance is required, it is important to perform maintenance operations correctly. Maintenance items, such as replacing cables, can have a significant impact on the probe card adapter’s performance. When performing maintenance, lubricate all o-rings using Vacuum Goop (from Swagelok™). Make sure to use adequate Vacuum Goop for lubrication, but do not over lubricate o-rings.

For maintenance of the probe pins, refer to documentation provided by the manufacturer of the probe pins.

The system can source high voltages at current levels that can result in personal injury or death. Turn off power to system before performing any maintenance procedure.

Mechanical disassembly Disassembly of the probe card adapter is required when replacing DUT cables or when maintenance is required to the mother board.

When assembling the probe card adapter, use Vacuum Goop (from Swagelok) to coat all o-rings.

4-2 9139A-901-01 Rev. E / February 2015

To disassemble the probe card adapter, use the following procedure:



If time and space are available, it is possible to disassemble the probe card adapter without disconnecting the DUT cables.

1. Place the PCA in a safe state by resetting the test equipment. 2. Turn the vacuum control box valve to the unload position. 3. Disconnect vacuum hose from the probe card adapter. 4. Disconnect the DUT cables from your system. 5. Remove the probe card adapter assembly from your prober. 6. Remove the light shield assembly (see Probe card adapter standard components (on page 2-1)). 7. Remove the Allen-head screws that secure the cable strain relief, for the cable being replaced or

moved. 8. Remove the probe card from the probe card adapter assembly (see Probe card removal

procedure (on page 3-9)).

Replacing plug-in type DUT cables The DUT cables are pre-assembled with connector pins installed at the factory. Replacement cables with pre-assembled connector pins are available through your Keithley sales office. When you install the replacement cable, note that three sizes of connector pins are used on each DUT cable. The smallest connector pin is installed on the source and measure conductors. A larger size connector pin is installed on the guard conductor. The largest connector pin is installed on the outer shield (ground) conductor.

To replace a DUT cable, perform the following procedure:

1. Place the PCA in a safe state by resetting the test equipment. 2. Disassemble the probe card adapter assembly (refer to Mechanical disassembly (on page 4-1)). 3. Insert connector pins of cable in sockets in mother board (see next figure). 4. Reassemble probe card adapter.

Figure 9: Model 9139A Replacing plug-in guarded-type DUT cables

Moving DUT cable connections



Typically prober pin #1 is connected to system pin #1, prober pin #2 is connected to system pin #2, etc. If an application requires different connections, you can connect the prober pins to other system pins.

If you have a Keithley S500 Series system, each DUT cable is independently connected to the matrix. Therefore, to move a DUT connection, you simply unplug the DUT cable from the matrix.

System pin is defined as a node or crossbar in the matrix of your parametric test system.

Cleaning Cleaning is important to ensure accurate low current measurements. The cleaning process removes contamination that causes shunt resistance (leakage) between measurement paths.

Contamination can take many forms. Some sources of contamination are:

• Residue remaining after incomplete cleaning. • Residue after using an improper or contaminated cleaning fluids. • Residue from fingerprints (see Handling precautions (on page 3-2) for more information). • Flux from soldering. • Condensation from room conditions which do not meet Keithley specifications.

Observe the following precautions when it is necessary to use solder on a circuit board:

• Use an OA-based (organic activated) flux, and take care not to spread the flux to other areas on the circuit board.

• Remove the flux from the work areas when the repair has been completed. Use pure water along with clean foam-tipped swabs or a clean soft brush to remove the flux.

• Once the flux has been removed, swab only the repaired area with methanol, then blow dry the board with dry nitrogen gas.

• After cleaning, the board should be allowed to dry in a 50°C low-humidity environment for several hours.

Replacing pogo pins



Model 9139A-PCA Probe Card Adapter Instruction Manual Section 4: Model 9139A Maintenance

9139A-901-01 Rev. E / February 2015 4-5

To replace a pogo pin, use the following procedure:

1. Reset the tester hardware. 2. Remove the probe card from the probe card adapter assembly (see Probe card removal

procedure (on page 3-9)). 3. Remove the defective pogo pin. Grab the pin with a pair of needle-nose pliers. Pull the pin out of

its socket.

The pogo pins are not symmetrical. Damage to the socket may occur if the pogo pins are inserted incorrectly.

4. Locate the rounded end of the replacement pogo pin (see the next figure). Insert the rounded end of the pin into the socket. The double-chisel tip, located on the other end of the pogo pin, must protrude out of the socket. This end of pogo pin contacts a pad located on the probe card.

5. Re-install probe card.

Figure 10: Model 9139A Orientation of pogo pin and socket

Replacing a pogo pin socket If a pogo pin breaks off in a socket or if the pin becomes lodged in a socket, the pogo pin socket can be replaced. To replace a socket, use the following procedure:




4-6 9139A-901-01 Rev. E / February 2015

1. Follow the steps in Mechanical disassembly (on page 4-1) to disassemble the probe card adapter.

2. Locate the defective pogo pin or socket assembly. 3. Locate the pad where the defective socket is soldered to the mother board. This pad is on the

probe ring side of the mother board (refer to Probe card adapter standard components (on page 2-1)).

4. Unsolder the socket from the probe ring side (refer to Probe card adapter standard components (on page 2-1)) of the mother board.

Do not apply excessive heat when de-soldering socket. Excessive heat can melt the retention ring of the probe card adapter.

5. Remove the unsoldered pin. Push the end of the socket that protrudes through the mother board. Grab the other end of the socket with a pair of needle-nose pliers. Pull the socket out of its hole in the retention ring.

6. Remove residual solder from hole of solder pad. 7. Insert the small end of the replacement socket into the hole located in the retention ring (see

previous figure). Slide the socket into the hole until the bottom of the socket is flush with the surface of the retention ring (pogo pin not installed in socket).

8. Confirm that the socket is installed properly (see previous figure). The small end of the socket protrudes through the hole on the mother board. The open end of the socket is flush with the surface of the retainer ring.

9. Solder the socket to the pad located on the mother board. 10. Install a pogo pin into the socket. 11. Clean the flux from the solder connection (see Cleaning (on page 4-4) for more information). 12. Re-install the probe card.

Replacing vacuum connection The probe card adapter's vacuum connection can be replaced if damaged. Remove the vacuum connection. Make sure all old sealant is removed from threaded holes on probe card adapter. Lightly apply standard pipe sealant to new vacuum connection and install. Do not overtighten connection.
